Because you don't need fink for most things using the Mac OS X 10.7 binaries (which work on 10.8), I've been telling people to not use fink and instead install homebrew to get the necessary libraries. All you need is Xcode to begin.
1. Install Homebrew: ruby -e “$(curl -fsSL [
raw.github.com])”
2. Install PyQT: brew install pyqt
3. Set Python Path: export PYTHONPATH=/usr/local/lib/python2.7/site-packages:$PYTHONPATH
3a. Consider adding the above line to your .bashrc or .profile (assuming Bash Shell)
4. Run any AFNI uber_*.py programs
5. Rejoice in the fact that you can delete the fink folder and never have to struggle with it again!
